Insinuates is the correct word here, as the article dances around the point without providing much evidence. I can believe that people with sun exposure tend to be healthier. But at no point does the author make the case that these people would be even healthier if they didn’t use sunscreen. The link is tenuous at best, and the whole sunscreen part seems thrown in to genrerate a headline.
Eh, the author did give some examples of bad chemicals in some sunscreens, so it's possible that there are negatives to using them.
Here's what I took away:
- don't use sunscreen most of the time (though if you care about aging effects, go for it on your face)
- avoid getting sunburns, and use sunscreen as necessary given your desired time in the sun
- check labels of sunscreen and get familiar with the common active ingredients
That's basically what I do already, though I'm going to make an effort to spend more time in the sun because I work at home, and therefore get minimal sun exposure normally.
